VEHICLE-LIFT.

To all 'whom t may concern:

Be it known that I, ALBERT I). SOLLENDER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Vehicle-Lift, of which the following is a specification.

This invention relates to vehicle lifts adapted especially for raising and lowering motor vehicles by means of a demountable and portable device to and from a suitable height to allow work and repairing to be conveniently carried on without the use of a pit with its numerous disadvantages.

The further object of this invention is to provide an absolutely sure and safe device for raising and lowering the vehicle which will be operated by the weight of the vehicle.

It will be readily seen that this device has many advantages over a pit in that it is cleaner, more accessible to light, more convenient for work, does not permanently occupy space and may be used where a pit could not be constructed, and may be moved from place to place.

In the drawings, Figure l is a side elevation of the vehicle lift showing the trackway .in a position to receive the vehicle. Fig. 2 isa plan View of the lift.

The lift consists of two identical units, parallel spaced and held at the proper distance by means of spacing rods. ItV may be constructed in various sizes and the construction or means of holding parts together modified from that shown in the drawings without departing from the principle of my invention.

The reference numeral l designates the base of each of these units onwhich is mounted a horse 2 fastened to the base but detachable. Jacross this horse is centrally hinged a tilting ti'ackway 3 as shown, with flanges to guide the wheels, of sullicient length to support the vehicle and to reach the floor and form an incline of suitable pitch. The trackway may be detached by removing the pin from the hinge. 0n the base l near each end is mounted a vertically disposed cylinder` 4. In each of said cylinders is a piston 5 provided with a connecting rod 6 extending upward to the trackway, said rods being attached to the piston and trackway by means of a pivot joint easily detachable from the trackway. The

Specification of Letterslatent.

two cylinders are connected by a pipe 7 provided with a valve 8. The chamber of each cylinder below the piston is filled with a sustaining fluid lsuch as oil or water. The pipe connected into the bottom of the chamber allows the fluid to flow from one cylinder to the other. rlwhe bases and trackways of the two units are connected and held at the proper distance by spacing rods 9 and l0 respectively, the rods being easily detachable. Approximate to each end of the trackways is a hinged leg 1l to give support when the trackways are in a horizontal position.

The operation of my device is substantially as follows: The vehicle to be repaired is driven up the inclined trackway 3 when the trackway is in position shown in Fig. l, or if the vehicle is without power it is pulled up by means of a block and tackle or other leverage attached to the ends of the trackways or to a point outside of the device. When the greater weight of the vehicle passes the center and the valve 8 is opened the fluid will be forced from the front cylinder, which then bears the greater weight, into the rear cylinder. The trackways and vehicle will thus gradually descend to a horizontal position where it may be sustained by closing the valve or by allowing it to rest on the leg. when it is desired to descend, thus throwing the weight to whichever end it is desired to lower. By then opening the valve and folding the leg it will slowly lower itself for disniounting. By closing the valve the vehicle may be held at any angle. Blocks or other device will be used to prevent rolling of the wheels while the trackway is inclined.

I-Iaving thus described my invention what I claim and desire to secure by Letters Patent is:

1. In a vehicle lift the combination of two units parallel spaced, each including a base supporting a horse upon which is hinged a tilting trackway, a cylinder and piston at each side of the pivot of said trackway, and a connecting duct between said cylinders, whereby the fluid contained in the cylinders may pass from one cylinder to the other as the trackway rocks, and means for controlling the flow of the liquid.

2. In a vehicle lift the combination of two identical unit-s parallel spaced9 each consist- The vehicle may be shifted,v
